Influence of Biophysical Parameters on Maintaining the Mesenchymal Stem Cell Phenotype

The maintenance of the mesenchymal stem cell (MSC) phenotype in vivo is influenced by the precise orchestration of biochemical and biophysical signals in the stem cell “niche”. However, when MSCs are removed from the body and expanded in vitro, there is a loss of multipotency. Here, we employ micropatterned hydrogels to explore how biophysical cues influence the retention of MSC multipotency marker expression. At the single-cell level, soft...
